The paper introduces a new voltage indicator to image sub-millivolt membrane potentials and discovers bioelectric contact inhibition mediated by gap junctions.

This study shows that Kir2.1 channels and voltage-sensing domains can co-assemble into functional KV-like complexes, altering voltage-dependent fluorescence responses.

This paper evaluates genetically encoded voltage indicators using FLIM to measure absolute membrane potential, finding that rEstus-NI provides the highest sensitivity and accuracy.

This study identifies MgPpIX as a potent and specific inhibitor of hNaV1.5, which suppresses cancer cell migration.
